Cov yeeb nkab steel yog ib hom hlau nrog hollow seem, nws qhov ntev yog ntau dua li txoj kab uas hla lossis ib ncig.Nws muab faib ua ncig, square, rectangular thiabtshwj xeeb-zoo li tus steel kavraws li cov duab seem;Nws tuaj yeem muab faib uacarbon structural steel yeeb nkab, low alloy structural steel yeeb nkab,alloy steel yeeb nkabthiab puas steel yeeb nkab raws li cov khoom siv;Nws tuaj yeem muab faib ua cov kav hlau xa mus rau cov kav xa dej, cov qauv tsim vaj tsev, cov khoom siv thermal, kev lag luam petrochemical, kev tsim cov tshuab, geological drilling, cov cuab yeej siv siab, thiab lwm yam;Raws li cov txheej txheem ntau lawm, nws tuaj yeem muab faib ua seamless steel yeeb nkab thiab welded steel yeeb nkab.Seamless steel yeeb nkab tuaj yeem muab faib ua kub dov thiab txias dov (kos duab).Welded steel yeeb nkab tuaj yeem muab faib ua ncaj seam welded steel yeeb nkab thiab kauv seam welded steel yeeb nkab.
Cov yeeb nkab steel tsis yog tsuas yog siv los thauj cov kua dej thiab cov hmoov av, sib pauv lub zog hluav taws xob, tsim cov khoom siv kho tshuab thiab ntim khoom, tab sis kuj yog cov hlau lag luam.Siv cov yeeb nkab steel los tsim cov qauv vaj tsev, ncej thiab cov cuab yeej txhawb nqa tuaj yeem txo qhov hnyav, txuag 20 ~ 40% ntawm cov hlau, thiab paub txog kev tsim kho tshuab.Kev siv cov yeeb nkab steel los ua cov choj loj tuaj yeem tsis tsuas yog txuag cov ntaub ntawv steel thiab ua kom yooj yim rau kev tsim kho, tab sis kuj txo qis thaj tsam ntawm kev tiv thaiv txheej, txuag peev thiab kho cov nqi.
Los ntawm txoj kev tsim khoom
Raws li txoj kev tsim khoom, cov kav dej steel tuaj yeem muab faib ua ob pawg: seamless steel kav thiabwelded steel kav.Welded steel kav yog hu ua welded kav rau luv luv.
1. Seamless steel tubestuaj yeem muab faib ua cov raj kub dov seamless, txias drawn tubes, precision steel tubes, kub expanded hlab, txias spun raj thiab extruded raj raws li ntau lawm txoj kev.
Seamless steel kavyog ua los ntawm high-zoo carbon steel los yog alloy steel, uas yuav ua tau kub dov los yog txias dov (kos).
2. Welded steel kav tau muab faib ua rau hauv cov kav dej rauv welded, hluav taws xob vuam (tsis kam vuam) cov kav dej thiab cov kav dej tsis siv neeg arc welded vim lawv cov txheej txheem vuam sib txawv.Lawv tau muab faib ua cov kav dej ncaj nraim thiab cov kav dej sib txuas vim lawv cov ntaub ntawv sib txawv.Lawv cov duab kawg kuj tau muab faib ua cov kav welded thiab tshwj xeeb-puab (square, ca, thiab lwm yam) welded kav.
Welded steel kav yog welded los ntawm dov steel daim hlau nrog pob tw los yog kauv seams.Nyob rau hauv cov nqe lus ntawm kev tsim, lawv kuj tau muab faib ua welded steel kav rau kev thauj mus los tsis tshua muaj siab kua, muab kauv hluav taws xob welded steel kav, ncaj dov welded steel kav, hluav taws xob welded kav, thiab lwm yam. Seamless steel kav yuav siv tau nyob rau hauv ntau yam industries, xws li kua thiab roj pipelines.Cov yeeb nkab vuam siv tau rau cov kav dej, cov yeeb nkab roj, cov yeeb nkab cua sov, cov yeeb nkab hluav taws xob, thiab lwm yam.
Cov yeeb nkab steel tuaj yeem muab faib ua cov yeeb nkab carbon, hlau yeeb nkab, cov yeeb nkab steel hlau, thiab lwm yam raws li cov khoom siv yeeb nkab (xws li hom hlau).
Cov kav dej carbon kuj tuaj yeem muab faib ua cov pa roj carbon zoo tib yam cov kav dej thiab cov kav dej carbon zoo.
Alloy yeeb nkab tuaj yeem muab faib ua cov yeeb nkab uas tsis tshua muaj hlau, cov yeeb nkab steel hlau, cov yeeb nkab siab thiab cov yeeb nkab muaj zog.Cov kabmob, kub thiab acid resistant stainless hlau raj,precision seamless steel rajthiab kub kub alloy raj.
